ABSTRACT:
Data processors, each comprising a distributed processing system, include means for executing checkpoint restart processing synchronously with each other. Each of the data processors erases old checkpoint data when it can execute restart processing based on new checkpoint data. When one of the data processors cannot execute the restart processing based on the new checkpoint data, the other of the data processors executes the restart processing based on the old checkpoint data synchronously with the one of the data processors.
